Hierarchical Context-based Pixel Ordering
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a context-based scanning algorithm which reorders the input image using a hierarchical representationof the image. Our algorithm optimally orders (permutes) the leaves corresponding to the pixels, by minimizing ...
Context-based Space Filling Curves
(Blackwell Publishers Ltd and the Eurographics Association, 2000)
A context-based scanning technique for images is presented. An image is scanned along a context-based space filling curve that is computed so as to exploit inherent coherence in the image. The resulting one-dimensional ...
Automatic Camera Placement for Image-Based Modeling
(Blackwell Publishers Ltd and the Eurographics Association, 2000)
We present an automatic camera placement method for generating image-based models from scenes with known geometry. Our method first approximately determines the set of surfaces visible from a given viewing area and then ...
Competing Fronts for Coarse-to-Fine Surface Reconstruction
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
We present a deformable model to reconstruct a surface from a point cloud. The model is based on an explicit mesh representation composed of multiple competing evolving fronts. These fronts adapt to the local feature size ...
A Part-aware Surface Metric for Shape Analysis
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
The notion of parts in a shape plays an important role in many geometry problems, including segmentation, correspondence, recognition, editing, and animation. As the fundamental geometric representation of 3D objects in ...
Locally Adapted Projections to Reduce Panorama Distortions
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Displaying panoramic and wide angle views on a flat 2D display surface is necessarily prone to distortions. Perspective projections are limited to fairly narrow view angles. Cylindrical and spherical projections can show ...
